IS Https://IP/query support HTTP/3 ?

I'm use host to request https://MyHost/ the networkProtocolName return "h3"

assumesHTTP3Capable = YES

- (void)URLSession:(NSURLSession *)session
       task:(NSURLSessionTask *)task
didFinishCollectingMetrics:(NSURLSessionTaskMetrics *)metrics AF_API_AVAILABLE(ios(10), macosx(10.12), watchos(3), tvos(10))
{
for (NSURLSessionTaskTransactionMetrics * m in metrics.transactionMetrics){
       
     if(m.networkProtocolName.length > 0){
        NSLog(@"networkProtocolName %@", m.networkProtocolName);
        break;
      }
    }
}

but when I use ip replace MyHost to request, and add MyHost to http header @{@"host": "ip"}, the networkProtocolName return "h2"

- (void)URLSession:(NSURLSession *)session
       task:(NSURLSessionTask *)task
didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge
 completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential *credential))completionHandler
{
 NSURLSessionAuthChallengeDisposition disposition = NSURLSessionAuthChallengePerformDefaultHandling;
    NSURLCredential *credential = nil;


   //get header host replace ip
    NSString *host = [[task.currentRequest allHTTPHeaderFields] objectForKey:@"host"];
    if (!host) {
      host = task.currentRequest.URL.host;
    }
    if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]) {
      if ([weak evaluateServerTrust:challenge.protectionSpace.serverTrust forDomain:host]) {
        disposition = NSURLSessionAuthChallengeUseCredential;
        credential = [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust];
      } else {
        disposition = NSURLSessionAuthChallengePerformDefaultHandling;
      }
    } else {
      disposition = NSURLSessionAuthChallengePerformDefaultHandling;
    }


    // 对于其他的 challenges 直接使用默认的验证方案
    completionHandler(disposition,credential);
}

-(BOOL)evaluateServerTrust:(SecTrustRef)serverTrust forDomain:(NSString *)domain {


  //创建证书校验策略
  NSMutableArray *policies = [NSMutableArray array];
  if (domain) {
    [policies addObject:(__bridge_transfer id)SecPolicyCreateSSL(true, (__bridge CFStringRef)domain)];
  } else {
    [policies addObject:(__bridge_transfer id)SecPolicyCreateBasicX509()];
  }


  //绑定校验策略到服务端的证书上
  SecTrustSetPolicies(serverTrust, (__bridge CFArrayRef)policies);


  //评估当前 serverTrust 是否可信任，
  //官方建议在 result = kSecTrustResultUnspecified 或 kSecTrustResultProceed 的情况下 serverTrust 可以被验证通过，
  //https://developer.apple.com/library/ios/technotes/tn2232/_index.html
  //关于SecTrustResultType的详细信息请参考SecTrust.h
  SecTrustResultType result;
  SecTrustEvaluate(serverTrust, &result);


  return (result == kSecTrustResultUnspecified || result == kSecTrustResultProceed);
}

https://ip/ networkProtocolName return "h2" does ip request do not supprt HTTP/3?

hope to respone thank you.
